From the perspective of static and dynamic combination, the article based on the data of the fifth、sixth census and 1% sample survey in 2005, using quantitative and qualitative analysis, preliminarily analyzed spatial agglomeration, evolution trend and influencing factors of floating population since 2000. The study found: ①Since 2000,the floating population has had high degree of spatial agglomeration and presented the spatial distribution of "East High, Midwest low ";②Its spatial agglomeration nearly showed the feature and tendency of concentrating on east region, some of the western province (city/district) in the network association also showed obvious clustering feature,further analyzing the type of agglomeration found the floating population of the most province (city/district) belonged to the same class and mobility reasons was the dominant social characteristic; ③Since 2000,the factors have attracted floating population to urban agglomeration which mainly include economic level, transportation advantages, consumption and investment in space-based etc.%本文从动静结合的研究视角出发,以第五、六次人口普查及2005年1%人口抽样调查数据为基础,运用定量与定性的分析手法,初步解析了2000年以来全国流动人口的空间集聚程度、集聚特征、演变趋势及其影响因素.研究发现:①2000年以来全国流动人口的空间集聚程度较高且呈现出"东部高、中西部低"的分布特征;②流动人口的空间集聚特征在集聚分区、网络分析、人口重心中基本均表现出向东部地带集中的特征与趋势,其中西部的部分省(市/区)在网络关联中也表现出较为明显的集聚特征;进一步分析其集聚类型,发现绝大多数省(市/区)的流动人口属同一类且主导社会特征为流动原因;③吸引流动人口空间集聚变化的因素仍以经济水平、交通优势、消费能力和投资空间等为主.
